SOCKET \VBENCH.

Application filed December 31, 1919. Serial No. 348,691.

1 '0 all whom it may concern:

Be it known that I, WARREN S. Bnimows, a citizen of the United States,residing at ll orcester, in the county of vVOlCQStGl' and State of hlassachusetts, have invented certain new and useful Improvements inSocket l Vrenches, or which the following is a specitlcation.

This invention relates in general to socket Wrenches, and moreparticularly to improved means for rigidly securing the socket member tothe handle.

The present common method of securing the socket member of a socketwrench to a handle is to insert one end of the handle into a hole in thebase of the socket and then drill a hole transversely through both thebase of the socket and the handle, a pin be ing driven through said holeand riveted 0 therein so as to prevent turning of the handle in thesocket and hold the socket lirinly uponthe handle. This method andconstruction involves an unnecessary amount of time and expense, as wellas multiplying 5 the partsof the Wrench.

1 he objects of my invention are to provide improved means for rigidlyconnecting the socket and handle of a. socket wrench, and eliminate thetime, trouble and expense an incident to the use of a locking pin; toprovide a construction whereby the handle is positively prevented fromturning in the SOCl-Zll) member, and whereby the socket member isprevented from slipping oil the handle; to obtain such a constructionwhich is strong and durable and which will effectively withstand allstrains to which a 10b of this character is usuallysubjected; to securea construction whereby the handle and socket member may be connected ina single operation and without addition of other parts; to thus connectthe handle and socket member by mere upsetting 01' driving of the metalof the socket into the handle; and to obtain other objects and resultsas may be brought out by the following description.

Referring to the accompanying drawings in which like numerals ofreference indiwate the same parts throughout the several views,

Figure l is a side elevation of one type of socket wrench embodying myinvention;

nigure 2 is as similar view thereof, looking at the ends of the socketmembers;

Figaire 3is a vertical sectional View on the line of Figure 2; and

Figure l is a similar view on the line ll of Figure 2.

In the' specific embodiment of the invention illustrated by thedrawings, the numeral l designates the handle of the wrench formed of asolid round rod of metal. Upon each end of said handle is mounted in anysuitable position a socket member, adapted to engage over a nut or bolthead, the socket member 2 being of a size and configuration to lit onesize of nut, while the other socket 3 may be of a dilierent size to fitanother size of nut. Both sockets are similar in constructionandareapplied to the handle 1 in the same manner so that a description of thesocket member 2 will suflice for both.

T he socket member 2 may be arranged at any suitable angle to the handle1 and comprises a solid base portion 4: at one end there-- of, theopposite end of the socket member being formed with a polygonal shapedsocket 5 to receive a nut or bolt head. The solid base portion Aisprovided with a transverse ly disposed recess or hole 6 which extendsacross the axial center of the socket member and is adapted to snuglyreceive one end of the handle 1, as shown in Figures 3 and a.

In applying the handle 1 to the socket member, one end of the handle isinserted into said hole 6 in the socket member as -far as possible,after which a suitable sharp pointed tool (not shown) is inserted intothe one side of the handle, and the walls of the handle 1, so as to formin effect one piece. The play and looseness between the handle andsocket member which is incident to the use of a pin fastening means isthus eliminated, and a wrench constructed in accordance with myinvention will withstand all many other types of wrenches and tools.

Therefore, I do not wish to limit myself except as required by thefollowing claim when construed in the light of the prior art.

Having thus described my invention What I claim as new herein and desireto secure 1 by Letters Patent is:

In a socket Wrench, the combination of a socket member having therein anut engaging socket and a handle receiving hole, said handle receivinghole being located Within the solid base portion of the socket memberwith the axis of said hole crossing the axis of the nut engaging socket,and a handle inserted in said hole and held therein by an axiallylocated portion of the, socket member driven into engageni'ent'with saidhandle from within the 'nut engaging socket.

WARREN s. BELLOWS.
